Abstract

A method and apparatus for applying a sealant includes a first chamber that retains a first substance. A second chamber retains a second substance, wherein the second chamber is in selective fluid communication with the first chamber. A third chamber retains a third substance. A first actuator is configured to cause fluid communication of the first and second chambers to allow the first and second substances to comingle and form a first mixture. A second actuator is configured to urge the first mixture and the third substance out of the sealant application apparatus.

 a first actuator configured to cause fluid communication of the first and second chambers to allow the first and second substances to comingle and form a first mixture; and 
 a second actuator configured to urge the first mixture and the third substance out of the sealant application apparatus. 
 
     
     
       2. The sealant application apparatus of  claim 1 , comprising a mixing chamber configured to receive and mix the first mixture and the third substance into sealant mixture prior to being urged out of the sealant application apparatus. 
     
     
       3. The sealant application apparatus of  claim 1 , comprising an atomizing nozzle configured to spray the first mixture and the third substance out of the sealant application apparatus. 
     
     
       4. The sealant application apparatus of  claim 1 , comprising a burst disc fluidly separating the first and second chambers, wherein actuation of the first actuator causes the burst disc to rupture to allow fluid communication of the first and second chambers. 
     
     
       5. The sealant application apparatus of  claim 1 , comprising a valve fluidly separating the first and second chambers, wherein actuation of the first actuator allows the first or second substance to pass therethrough to allow fluid communication of the first and second chambers. 
     
     
       6. The sealant application apparatus of  claim 5 , wherein the valve comprises a one-way check valve. 
     
     
       7. The sealant application apparatus of  claim 6 , wherein actuation of the first actuator urges the second substance through the one-way check valve and in to the first chamber to mix with the first substance. 
     
     
       8. The sealant application apparatus of  claim 1 , comprising a fourth chamber including a fourth substance, wherein the fourth chamber is in selective fluid communication with the third chamber. 
     
     
       9. The sealant application apparatus of  claim 8 , wherein the first actuator is configured to cause fluid communication of the third and fourth chambers to allow the third and fourth substances to comingle and form a second mixture. 
     
     
       10. The sealant application apparatus of  claim 8 , wherein a second actuator is configured to cause fluid communication of the third and fourth chambers to allow the third and fourth substances to comingle and form a second mixture. 
     
     
       11. The sealant application apparatus of  claim 1 , comprising a lock configured to fix the second actuator with respect to the sealant application apparatus to inhibit inadvertent urging of the first mixture and the third substance out of the sealant application apparatus. 
     
     
       12. The sealant application apparatus of  claim 1 , wherein the first, second, and third substances comprise tissue sealant components. 
     
     
       13. The sealant application apparatus of  claim 1 , wherein a first syringe includes the first and second chambers. 
     
     
       14. The sealant application apparatus of  claim 1 , wherein a first syringe includes the first chamber, and a second syringe includes the second chamber. 
     
     
       15. The sealant application apparatus of  claim 1 , wherein a third syringe includes the third chamber. 
     
     
       16. The sealant application apparatus of  claim 1 , wherein the second chamber includes a spring-actuated plunger configured to urge the first mixture out of the second chamber and into the first chamber. 
     
     
       17. A method of using a self-contained sealant application apparatus, the method comprising:
 actuating a first actuator to allow a first substance of a first chamber to comingle with a second substance of a second chamber; 
 mixing the first and second substances to form a first mixture; and 
 urging the first mixture and a third substance of a third chamber together to mix to form a sealant mixture; and 
 urging the sealant mixture out of the application apparatus for application of the sealant mixture. 
 
     
     
       18. The method of  claim 17 , wherein mixing the first and second substances includes repeatedly actuating the first actuator to mix the first and second substances. 
     
     
       19. The method of  claim 17 , wherein mixing the first and second substances includes shaking the sealant application apparatus to mix the first and second substances. 
     
     
       20. The method of  claim 17 , wherein actuating the second actuator to urge the first mixture and the third substance together includes actuating the second actuator to urge the first mixture and the third substance into a mixing chamber to mix and form the sealant mixture. 
     
     
       21. The method of  claim 17 , wherein the urging steps are performed by actuating a second actuator. 
     
     
       22. The method of  claim 17 , wherein the urging steps are performed by actuating second and third actuators, respectively.
